Just a couple of suggestions for kid's Christian books this Christmas.
After reading some good reviews on the Jesus Storybook Bible and The Big Picture Story Bible, we have bought them for our kids this year.
There's a good series by Derek Prime called "Sarah & Paul" for kids aged 4-7. Although they're engaging fictional stories, each book focuses on a biblical theme: for example, what does it mean to be a Christian, the 10 Commandments, the Lord's Prayer, what is God like? and baptism. Glen received these last Christmas and is beginning to enjoy them already (he turned 4 in August).
I'd also recommend Sinclair Ferguson's Big Book of Questions & Answers. We are looking forward to using this with Glen this coming year. As you know, kids are FULL of questions and this family guide to the Christian Faith contains a wealth of activities, prayers, and Bible references.
